Tristar Gold Exploration And PFS Update

Scottsdale, Arizona--(Newsfile Corp. - May 4, 2020) - TriStar Gold Inc. (TSXV: TSG) (OTCQB: TSGZF) (the Company or TriStar) is pleased to announce that delineation of upside drill targets outside the current resource base at its 100%-controlled Castelo de Sonhos gold project is advancing on schedule. Multiple near-surface mineralized conglomerate targets have been generated for future drill evaluation. Target delineation work has now shifted to generating deeper targets at CDS, which selection process is anticipated to be completed by June 2020. In addition to target generation, the Company is pleased to announce its infill reverse circulation drill program is now complete. The need for any follow-up drilling will be determined upon review of awaited final assays.

"Our exciting target generation work conducted with GoldSpot Discoveries has delineated multiple new shallow conglomerate gold targets for drill testing," says Nick Appleyard, TriStar's President and CEO. "Our geologists are currently evaluating the first round of these shallow open-pit targets in preparation for initial drill testing as soon as possible. Work on CDS deeper targets is ongoing and we anticipate it similarly generating multiple targets by the time work is completed in June."

Upside exploration targeting work has progressed past the data integration phase and the machine learning algorithms are advancing toward rapid interpretation of downhole imagery (OTV). Phase two, Conventional and Machine Learning target generation, is now underway. Initial targets are currently being reviewed by TriStar geologists. Phase two deep target generation is scheduled to be completed in June at which point, phase three, drill testing of the targets and completion of the 3d modeling, will begin.

Pre-Feasibility Study

The CDS pre-feasibility infill drill program concluded April 18th. A total of 183 reverse circulation drill holes encompassing 18,993m and 3 core holes encompassing 372m were completed. Reverse circulation drilling is substantially complete. It is anticipated that approximately a further 2,000m of core drilling, including geotechnical drilling, is required for the Company's pre-feasibility study. No assays were received during April; the next batch of results are expected to be received by the end of May.

The aim of TriStar's prefeasibility study is to refine the economic analysis of the CDS conglomerate gold deposit. TriStar's previously announced Preliminary Economic Assessment (see the Company's press release "51% IRR from PEA at TriStar Gold's Castelo de Sonhos Project", dated Nov 16, 2018) returned exceptional economics. Recent review of this study by the independent Qualified Person (QP) who conducted the study confirms that base-case inputs are still current in respect of a base case scenario even though gold prices and the Brazil Real exchange rate have changed significantly.

Base-case economics of the PEA in 2018 used a gold price of US$1,250/oz and resulted in a post-tax internal rate of return of 43% and net present value at a 5% discount of US$264 million. Updated gold price sensitivities are illustrated in Figure 2. The CDS project is also quite sensitive to changes in the exchange rate of the Brazilian Real to the US Dollar. The PEA base case applied an exchange rate of 3.8 Reals-to-US$1. The current exchange rate is approximately 5.4 Reals-to-US$1. Applying the current exchange rate and the base case gold price of $1,250/oz gold price results in an increase of the post-tax IRR from the base case of 43% to 60%.

Figure 2 NPV and IRR sensitivities with respect to changes in gold price, Brazilian real exchange rate has been kept at 3.8 Reals-to-$1.

The PEA and the above sensitivity analyses are preliminary in nature and include Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the economic results described in the PEA and the above sensitivity analyses will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
